Brentwood-based RegionalCare Hospital Partners is set to break ground by year's end on a 100-bed hospital in Sierra Vista, Ariz.

The new hospital falls under the terms of a long-term lease the company signed Tuesday with Sierra Vista Regional Health Center, an 88-bed hospital. Under terms of the deal, RegionalCare will take over immediate operations of Sierra Vista while the new hospital is being built on an adjacent 70-acre plot of land owned by the hospital. Construction is expected to take 18 months.

Under the deal terms, RegionalCare has committed $11 million in capital investments in existing Sierra Vista facilities, including the addition of cardiac cath services, and $18 million to recruit more than 25 physicians over the next seven years to supplement the existing medical staff. The overall value of the deal was not disclosed.
